Facebook groundhog
A person who checks Facebook just to make fun of everyone they used to know and act like they’re the only one who matters now.
"You used to be the best at everything. Now you’re just a loser.", said on a post about their new job.
"You still think you’re cool?", said after seeing a post about their new group of friends.
"You used to be the best at video games. Now you’re just sad.", said on a post about their new hobby.
